I met the same issue here.

OS: Windows 11/WSL/Ubuntu 22.04.4 LTS

A quick workaround would be to revert below commit.

I'm waiting for Ubuntu 24.04 for WSL, maybe then this issue will be fixed.

I faced the same issue using same Win 11 with Ubuntu 22.04.4 WSL , althought i did not install the riscv-gnu-toolchain for xv6. (i only ran this command 'sudo apt-get install git build-essential gdb-multiarch qemu-system-misc gcc-riscv64-linux-gnu binutils-riscv64-linux-gnu')

But using @Donglin-SHI solution made the qemu work.

WSL/Ubuntu 24.04.1 LTS was published at 2024-08-30.
After I upgraded Ubuntu to Win11/WSL/Ubuntu 24.04.1 LTS, this issue was solved.

Sometimes, WSL will encounter inexplicable errors
